Theory regards this opening as incorrect, but it is impossible to agree
with this. Out of the five tournament games played by me with the King's
Gambit, I have won all five. ~ David Bronstein

T

his position comes from the "Thematic tournament" that was played on Red Hot Pawn.

In the position on the right it is Black to move.

Answer below.

A thematic tournament is one where every game is started from the same opening position. In this case it was the "Pantelakis Counter Gambit of the King's Gambit", which I had never heard of.

A counter gambit occurs when black gambits a pawn of his own in response to White Gambiting a pawn.

This counter gambit occurs after the moves 1. e4 e5 2. f4 f5!?

This does not seem like a very sound move to me, but I have no doubt that it leads to some fun, and tactical games.

Often thematic tournaments will feature odd or off beat openings, that players do not feature on a normal basis, but want some practice playing against. In years of playing the King's Gambit, I have never seen the response 2. ..f5.

Answer:

11. ..Bg3+ is a check that discovers an attack against the undefended White Queen. This kind of attack where the bishop moves out of the way with check leaving an attack against a hanging Queen is actually very common. Often the checks are with the light squared bishops on the h2 and h7 squares. This is a good tactical motif to know.
